Emergency Keylock Actuator



Includes mounting flange but order contact blocks separately. To assure proper contact separation under all conditions, slow make/slow break contacts are recommended for emergency actuators. Foolproof model meets EN 418 directive.
New design prevents "teasing" the pushbutton actuator which can result in premature or unreliable contact operation. Also eliminates the possibility of blocking the pushbutton operation by lodging foreign bodies behind the actuator. To prevent rotation of the emergency stop switch, a special panel punch is available.
